KS3 Mathematics

For secondary school pupils (year 7-9) I use CGP KS3 Mathematics (levels 5-8). This book is really handy for an individual revision. It also contains answers. I have just ordered an accompanying book: Collins Revision - KS3 Mathematics. I reckon it will be really useful for any child approaching the end of Year 9 ( end of KS3 level). If your child is at this stage and still finds gaps in his knowledge, get into work before it is too late. It is much easier to revise mathematics at the end of Y9 than before the GCSE.

Don't forget these fractions!

1/2 and 1/4 are covered in primary schools, but fraction addition, multiplication, subtraction or division is not always. Don't let your child be caught on the exam unable to solve a simple problem like 1/2 * 4

Go to the any local library, browse KS2 maths books that they have on offer before you buy them and practise these "awful" fractions.
I would recommend browsing through any educational books before buying them, as your child may have strengths in totally different areas to his peers and you will be able to accommodate his needs more by buying more suitable books.
